SIGNAL-HORN AND LAMP.

To all whom itmag concern:

Be it known that I, PERCY WALKER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Signal-Horns and Lamps; and I do hereby declare the following to be a full, clear, and exact description signaling means, said lamp and audible signaling means having a common casing and giving the appearance of a lamp or hornand being arranged to permit the lamp to be clearly observed and the audible signaling means to be clearly heard.

An important object of my invention s to provide a device of the character described wherein the two elements usually necessary on vehicles particularly motorcycles, namely lamps and audible signaling means are combined in a compact arrangement within a shell or casing and readily and easily oper- I ated independently of each other.

Another important object of my invention is to provide a device of the character described which is simpl as to construction, reliableand efficient in operation, capable of being readily assembled and disassembled and which is cheap to manufacture.

The above and additional objects are accomplished'by such means as are illustrated in theaccompanying drawings, described in the following specification and then more particularly pointed out as claimed.

WVith reference to the drawings, wherein Y I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 1s a vertical sectional view taken through my improved device showing the same as'it would.

Application filed March 17, 1914. Serial No. 825,353.

- conical reflector 2 of the same shape approximately as the casing .1. The reflector 2 is supported within the casing 1 centrally therein in spaced relation thereto by means of a plurality of radially extending arms 3 that are secured to the casing 1 and reflector 2 at their ends. The inner endsof the arms 3 are secured adjacent the apex portion of the reflector 2 as clearly shown in Fig. 1 in the drawings. An electric lamp 4 is mounted in a socket 5 that is fitted within an aperture formed in the apexportion of the reflector 2. The lamp 4 is operatively connected with a battery or other suitable source of current after a manner which will be later more fully described.

' vide a screw cap which consists of an outer flange and threaded ring 8 that is turned upon the open end of the casing 1. An inner ring 9 of less circumference than the ring 8 is connected with the ring 8 by. integral connecting arms 10. The inner ring 9. is designed to fit over the outer face of the lens 7 adjacent the periphery thereof and thus clamps the lens in the proper position. The circumferential flange 11 similar to the one 6 is formed on the outer face. of the reflector 2 almost opposite the flange 6 and has suitably secured thereon the inner edge of an annular strip of foraminous material 12. A flange 13 formed on the inner face of the 'casing 1 adjacent to the open end thereof and which is similar to the one 11 has suitably secured upon the outer face thereof the outer edge of the strip 12. This strip of foraminous material 12 prevents dustand otheri' foreign matter getting into the easmg v The spacing of the reflector 2 with relation to the casing 1 provides an opening for the sound made by the audible signaling means to escape from the casing 1." The peculiar shape of the reflector 2 acts as a sound emitted from the casing 1 in such a Way that it will be clearly audible for a great distance. a

Mounted within the casing. 1 adjacent the 5 apex portion thereof and rearwardly of the .arms 3 is audible signaling means designated 14 as an entirety. This audible signaling means is connected in the electrical circuit for the lamp 4 and will be later more fully described.

The circuit for the audible signaling means la'and lamp 4: comprisesa battery 15 or other suitable source of current, that is connected by a conducting wire 16 to the lamp {and from the lamp 4 by a wire 17 to a suitable switch 18 that is secured upon the upper and outer face of the casing 1.

From the switch 18 a conducting wire 19 leads back to the other side-ofythebattery g0 15. It willthus be seenthat the circuit for I the lamp 4 iscomplete and may be controlled by the switch 18 which is readily accessible to the driver or rider as the case maybe.

A conducting wire 20 connects one pole of the battery 15 with the audible signaling means 14. A wire 21 connects the other pole of the battery 15 with a push button 22 .and from the push button 22 a wire 23 connects with the signaling means 14.

The push button 22 may be arranged at any desired point adjacent the drivers seat of the vehicle or upon the handle bars of a motorcycle as the case may be. It will be readily seen that by means of the switch 18 and push button 22 the lamp 4 and audible signaling means 14 may be suitably con trolled.

A suitable bracket 24 is secured upon the under face of the casing 1 and provides for the attaching of the device to a vehicle or motorcycle. The audible signaling means 14 comprises a suitable diaphragm 25 that is secured at suitable point by arms 26'that are secured at their ends to the periphery of the diaphragm and easing 1.

Suitably mounted within the casing 1 rearwardly of the diaphragm 25 are suitable electrical magnets 27. These magnets are 6 connected by the wire 23 leading from the push button 22 as clearly shown in the drawings. The magnets are electrically connected with each other by means of a conducting wire 27.

An armature plate 28 is arranged to 00- act with the magnet 27 and is connected intermediate its ends with a connecting rod 29 that is operatively connected at its outer end with the central portion of the diaphragm 25. I

A suitable bearing 30 is secured in any suitable manner to the casing 1 interiorly thereof and slidably receives the rod 29.

Secured at its ends to the ends of the armature plate 28 is a bowed spring 31 that is connects the screw 33 with one of the magnets 27 thus directly connecting the armature plate 28 in the circuit. A contact pin 36 is positioned within the casing 1 at a point adjacent to one end of the spring 31 and normally engages the spring 31. In this connection it will be noted that the wire 20 is directly connected with the pin 36 thus the circuit is completed and when the push button 22 is operated to close the circuit the magnets 27 will become energized drawing the armature plate 28 toward them and in so doing moves the spring 31 from the contact pin 36 breaking the circuit. The spring 31 is arranged so that when the armature plate-28 is drawn inwardly and the diaphragm 25 flexed or distorted the armature plate will be readily moved into normal position so that the spring 31 engages the contact pin 36. The return action is brought about by thesprin'g 31 and spring action of the diaphragm 25. It will be readily seen that the rapid movement of the rod 29 to and fro causes an audible signal to be readily produced. The sound Waves produced are deflected by the reflector 2 and cause the sound waves to be thrown from the casing 1 in such a way that the signal is audible for a great distance.

It will be readily seen with reference to the foregoing description and accompanying drawings that I have provided simple and inexpensive means for signaling and lighting a vehicle which is reliable in operation and simple as to construction.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth.

What is claimed is Y 1. In a device of the character described, a support, electromagnets, a circuit for said magnets, a sound diaphragm, a slidable armature, means operatively connecting said armature with the diaphragm, a spring secured at its ends to said armature, a sup- 1:0

meeaeo port for said spring rigidly secured thereto intermediate the ends thereof and a relatively stationary contact pin normally engaging said spring and operatively connected in said circuit, said spring being operatively connected with said circuit and arranged to move into and out of contact with said pin to open and close said circuit.

2. In a combined signal horn and lamp the combination with a shell having one end open, Within said shell, a spider within said shell and supporting the inner end of said conical reflector, illuminatin means within the re- 15 flector, audible signa lug means mounted bea conical elongated reflector mounted tween the closed end of the shell and inner end of the reflector, an inner ring mounted upon the open end of said reflector, an outer ring mounted upon the vopen end of said shell, arms connecting said rings with each other and xforaminous material arranged between said rings at the open end of said shell. v

In testimony whereof ll ailix my signature in presence of two witnesses.
